Subject: Re: a warning to implement
Date: Tue, 05 Feb 2002 19:26:00 -0000 [thread overview]
Message-ID: <20020206032518.6064BF28BE@nile.gnat.com> (raw)
<<In almost all cases, those are warnings that are useful in particular
(not uncommon) situations, but have drawbacks that prevent them from
being useful in the general case.
>>
And if this is not the case, I would consider adding them to -Wall :-)
The meaning of -Wall should be all warnings that meet the criteria that
Tim stated (very few false positives and easily silenced with an
equivalent construct). Note that my category of things that have clearly
undefined semantics should certainly meet this criterion, since
a) there should be certainly no false positives, in the sense that C code
should not contain any undefined constructs.
b) silencing them is always possible by replacing the incorrect code with
correct code :-)
